Cambodian officials have also expressed interest in launching direct flights between Manila and Phnom Penh.

The Philippines vice president met with Cambodian ministers during a trip to Phnom Penh for the state funeral and cremation of Cambodia's former king and head of state Norodum Sihanouk.

Relations between the two nations soured last year when Cambodia blocked efforts by the Philippines and Vietnam to mention their territorial dispute with China in the customary communique issued by the ASEAN at its ministerial conference.
